Application filed December 29, 1922. Serial No. 609,679.

T 0 all whom it may concern Be it known that I, THEODORE A. HOLM' BERG,a citizen of the United States, residing at Stamford, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Heating Systems, of which the following is aspecification.

My invention relates to improvements in heatlng systems, and moreparticularly to that class or type in which the hot air is positivelycirculated or forced from the source of heat or combustion chamber intothe heat distributing pipes or laterals through the medium of suitablebranch pipes or conduits communicating with an air receiving anddistributing manifold, the

latter being provided with a main or feed pipe communicating with asuitable fan or air circulating device adapted to circulate the air intothe manifold and through the branch pipes into the main heatdistributing pipes or conduits leading to the respective rooms or partsof the building structure to be heated.

The invention further relates to an improved heat generating unit orcasing provided with a suitable combustion or heat generating chamber,together so with an improved air receiving and distributing unit ormanifold arranged within said heat generating casing or unit, said airreceiving and distributing manifold being adapted to provide for aforced circulation of hot air through the branch or heat distributingpipes and to the respective rooms or parts of the building to be heated.

The primary object of the invention is to provide an improved heatingsystem adapted to to positively force or circulate'the heated airthrough the medium of improved heat generating and air receiving anddistributing units arranged and cooperating with each other in animproved manner.

There are other features of the invention residing in elementalcombinations and particular construction of parts, all as willhereinafter more fully appear.

With the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement and combination of parts,hereinafter described, illustrated in some of its embodiments in theaccompanying drawings, and particularly pointed out inithe appendedclaims.

prises a suitable heat generating unit or Referring to the drawings,forming a part of this s ecification, Figure 1 is a side elevatlon o' aheating system constructed in accordance with this invention, the heatgenerating and air receiving and distributing units being shown incentral vertical section, and the circulation of the heat or products ofcombustion and of the heated air being shown by full and dotted linearrows, respectively. V p

Flg. 2, a top plan view, partly in horizontal section, of the units,detached, certain parts being broken away forfthe purpose of clearerillustration of the baflie elements.

Similar numerals of reference designate like parts throughout allthefigures of the drawings.

The improved apparatus for carrying my lmproved heating system intoeifect comflame enclosing casing 1, the latter being of any suitable andconvenient form and, in the present instance, comprising a main casing 1and a removable bottom section 1 the 'sections 1 and 1 being preferablyprovided wlth flanges adapted torbe detachablyconnectecl by means ofbolts 1", and nuts 1.

As a convenient means of suspending the heat generator or flameenclosing casing 1 from the-first floor 2, of the building or structureto beheated, suitable hanger rods 3, may be provided, said hanger rods 3being connected to suitable parts of the structure and connected to lugs1 of the main section 1.

As a means of supporting combustion within the generator casing 1 wherea gas burner 4 is provided, the bottom section 1 is provided Withsuitable air inlet openings 1".

As a means of more effectively heating, distributing and circulating theair, the generator casing or unit 1 is provided with an internallyarranged air receiving and dis tributing unit in the specific form of amani fold embodying a main head or body portion 5, communicating withbranch pipes 5 above and a main air feed or supply pipe 5" below. Thebranch manifold pipes '5 extend through suitably spaced openings in thetop of the enerato-r unit or casing l and the main supp y pipe 5 extendsthrough a centrally located opening in the bottom of p the casing 1. Thebranch pipes 5 are adapted ,to be connected to a suitable number of heatdistributing pipes or conduits 6, the V119 latter being adapted to leadto suitable register casings or boxes 6", provided with suitable flooror wall registers as may be required.

As a means of effectively diverting and distributing the air as receivedfrom the main or supply pipe 5 the manifold head is provided with aconical shaped spreader head 5, and as a means of providing for theescape of the products of combustion where a burner is used (Or the heatwhere some other heating medium is used) the top of the generator unitor casing 1 is provided with a central opening 1, leading to a suitabledischarge pipe or flue 1 As a means of diverting the products ofcombustion or heat over and between the v branch pipes 55 for moreeffectively heating the latter, upper and lower baffle plates 7 and 8,respectively, are provided, together With an intermediate baffle plate9. In the present instance, the upper baiiie plate 7 is suspended bymeans of arms 7 extending from the upper wall of'the casing 1 and thelower bafiie plate 8 is supported-by means of supporting legs 8 restingon the spreader head 5 of the manifold. If desired, the intermediatebafiie plate 9 may be formed as a part of the generator casing or unit1, as shown, and it will be seen that the intermediate baffle plate 9 isprovided with a central opening 9 The outer periphery of theintermediate baffle plate 9 is provided with suitably spaced openingsadapted to removably receive and contain the branch manifold pipes 5 andthe upper baffle plate 7 is providedwith suitable curved orsemi-circular shaped openings to receive the upper ends of the branchpipes while the lower bai'lie plate 8 is provided. with suitably spacedopenings 8*, to receive and take over thes'aid pipes 5 If desired, theinterior portions of the branch pipes 5 may be provided with oppositelyarranged and extending semi-circular shaped baffles 5 the latter servingto retard and more effectively heat the heated air as it passes upwardlythrough the manifold pipes.

The main air supply or feed pipe 5 may communicate with a suitable airconduit pipe leading to a suitable source of air pressure or aircirculating means, such for example,as a fan, or the like, and operatedin a suitable manner, said air conduit pipe being preferably suppliedwith air from the exterior of the building to be heated.

As a means of lighting the gas burner 4, a separate nozzle 10 may beprovided, said nozzle communicating with a small gas pipe 11, and beingprovided with a valve 10 the nozzle 10 being adapted when lighted todirect a gas jet into the opening 1 in'the casing and which nozzle 10may also be used, if desired, as a pilot light.
